WorldView
The newest commercial high resolution imaging system, launched September 18, 2007, featuring 41 cm resolution.
WorldView-1 launched September 18, 2007 by DigitalGlobe will be the most agile satellite ever flown commercially. View WorldView-1 launch images and video. The high-capacity, panchromatic imaging system features 41cm resolution imagery (resampled to 50 cm for non-US Government customers). Operating at an altitude of 496 kilometres, WorldView-1 will have an average revisit time of 1.7 days and will be capable of collecting up to 750,000 square kilometres (290,000 square miles) per day of half-meter imagery. The satellite will also be equipped with state-of-the-art geo-location accuracy capabilities and will exhibit stunning agility with rapid targeting and efficient in-track stereo collection.

WorldView-2 is anticipated to launch in mid-2009. Operating at an altitude of 770 kilometres, WorldView-2 will offer half-meter panchromatic resolution and 1.8-meter multispectral resolution. WorldView-2 will have an average revisit time of 1 day and will be capable of collecting up to 975,000 square kilometres (376,000 square miles) per day of half-meter imagery. WorldView-2 will incorporate the industry standard four multispectral bands (red, blue, green and near-infrared) and will also include four new bands (coastal, yellow, red edge, and near-infrared 2).
